Letters Patent No. 102,864, dated May 10, 1870. l

IMPROVEMENT IN ALARM-Trans.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern l Be it known that I, EDEN REED, of St. Louis, 4in the county of St. Louis and State of Missouri, have made lcertain new and useful Improvements in` Alarmenable those herein skilled to make and use my" said invention, I will now in'ore fully describe the same. Figure lis a bottoni plan of the lid of the till,4 which is usually a counter or shelving top-board.

Figui-e2 is a sectional elevation of the till and its attachments. Y

Figure 3 is an elevation of the front end of the drawer, showing the metallic detent, and yFigure 4 is a horizontal section, showing the key- 'bars in plan viewA My said devices are applicable` to various forms of drawers and similar' receptacles. VThe more usual application to the ordinary v,money-drawers under tables or counters is illustrated in the figures. The drawer A slides in or out so as to be covered or accessible, as desired, under the cover-board B.

y. The front (usually vertical) drawer-board Ais made o'fstroug l'naterial, so as to contain the keys C, of' which `there may be any number required for any desired number of combinations in opening; said keys are stout metallic bars, standing verlically. 'lhe keys have their heads c cut to present t-he projections c', which are at the edges ofthe head surfaces.

LiVithin the'board A is the detent-plate D, `having the wide opening d, and proper guiding-edges fl; the

' 'plfate is firmly secured to the board .On the under sideof the cover-board B is a guideplate, E, which guides the tumblers F in their horizontal play. The number of tumblers corresponds to the number of keys,vv and a rock-shaft, f, passing through the rear ends of the tumblers, connects all of them-with the spring G.

The rock-shaft f is immediately under a rod, g, which has a projection g.

The rod g, as well as the spring G, is connected with the strikcr'LLthe arm of which is` pivot-ed at h, and which sounds the alarm on the bell I.

It is plain that the action ofthe spring G is to draw the tumblers F back to limit this play. The plate E has a slot, c, against the edge of which one or more tumbler-s imping'es, by a suitable stop, f1. The stop f2, at the rear of the tumblers, impingin'g against the rear edge of the plate E, limits the play iu the other directions.

The tumblers F have arrow-shaped heads. The heads f drop beyondI the detent-plate D, thus locking the drawers.

,/If`, now, the attempt is made to open the same wrongfully, then the drawer will moveforward slightly,

drawing the tumblers -F out, until the rock-shaft f, in

its radial movement, is compelled to leave the projection g', whereupon the spring G causes the alarm to sound.

In opening the drawer properly the keys C, by their projections c, will raise the tumblers, but such keys must be operated together whose projections stand 'beyond the thickest parts of the arrow-heads j"3 of the tumblers, as those keys which stand reversed, or so that their projections c' are next to the detentplate D, will prevent the tumblers above them from dropping to alock.

The devices thus arranged are simple and efficient,

and their economical construction and durability gives them advantages over many more costlydevices.

Having thus fully described my invention,

What I claim isl. The combination of the tumblers F, the rock shaft j, rod g, projection g', the spring G, and alarm device H I, substantially as and for the purpose set forth.

\2. The combination of the detent D, tumblers F,

f3, and keys C c c', operating and arranged substantially as set forth.

In testimony of said invention I have hereunto set my hand in the presence of- EDEN REED.
